* Performance: Airtightness Lv.1 / Watertightness Lv. 50 (Tested and certified by KS accredited testing facilities)



Q. Can existing glass be used?
A. Drilling holes in the existing glass poses a risk of breakage, and for optimal performance in terms of wind pressure resistance, insulation, airtightness, and watertightness, new glass needs to be manufactured.


 
Q. Can the vents be installed on double or triple glazing?

A: Yes. The vents can be installed on double- or triple-glazed glass up to 48mm thick. We provide glass that meets the site's wind pressure and insulation conditions.


Q. Who handles the installation?
A. The glass is installed by the window contractor you specify, with installation by us available if needed. A manual is provided if you choose to install the vents yourself.


Q. Can I have the glass made by a third party company?
A. To ensure quality, we manufacture and supply the glass. For single-glazed glass, you may choose to have it produced by another glass company to match the aperture size.


Q.Is it possible to buy just the vents without the glass?
A. For single-glazed glass, you have the option to purchase the vents alone.


Q. How many vents need to be installed for ventilation?
A. The recommended minimum number of the vents for installation is two, and it's advised to have at least one vent per 20m³ of room volume. Keep in mind that ventilation capacity decreases by 50% when using the filter.






Q. Can UBLO window be installed on non-glass walls?
A. The vents can be installed on smooth surfaces (glass, polycarbonate, coated wood, or metal panels) with a thickness of 8–48 mm. Airtightness may be difficult to ensure on rough surfaces, such as concrete walls.



Q. Does the vents not change color to yellow overtime?
A. The vents are made from highly robust and durable polycarbonate material, LG LUPOY 1303, which includes UV inhibitors. Although there might be a slight color change overtime, there are no concerns regarding its durability or functionality.
